Natural language search, however, is likely to regard irrelevant documents including coordinate words of terms in a query as relevant ones. To solve the above problem, this paper proposes a non-existence term which means that a document does not describe information. For instance, the non-existence term “pigeon → damage” extracted from the document D means that the document D does not describe “damage of pigeon.” Non-existence terms are generated by using coordinate words extracted from an ordinary dictionary and Wikipedia, and allow search engines to rapidly detect irrelevant documents. We evaluated the effectiveness of non-existence terms using the test collection constructed by NTCIR-3/4 competition. Experimental results showed that the proposed method achieved 82.9% in precision for irrelevant document detection.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"7","bibliographic_titles":[{"bibliographic_title":"研究報告音声言語情報処理（SLP）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-05-09","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"15","bibliographicVolumeNumber":"2011-SLP-86"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"id":74066,"updated":"2025-01-21T21:42:59.572869+00:00","links":{},"created":"2025-01-18T23:31:45.473366+00:00"}
